Yep, sure looks like a movie star baby! During a trip to Rio de Janeiro, Brazil, Brian Austin Green offered up the first glimpse of Noah Shannon, his 4-month-old baby boy with wife Megan Fox. Seen from the balcony of their hotel, Green, 39, held little Noah -- who sports puffy cheeks and pouty lips like his world-famous mom.

In another photo from the family's Brazilian trip, Fox, 26, looked slim and absolutely radiant in a short floral spring dress and red designer heels alongside her husband of two and a half years as they visited a Samba School in Sao Paulo. The happy couple sat and watched locals do a demonstration of "capoeira dance."

This Is 40 actress Fox has been frank with the media about how transformative first-time motherhood has been. "The whole thing has been overwhelming because I didn't realize you could love something so much, and I know people always say that but I love him so much it hurts," Fox said in December, "and it's an interesting feeling to have because I never felt that before."
